Lesson 6.4: Logical indexing in MATLAB

[@prashanthu_pdtr]

Very Informative video, showed how to optimize using index in very well manner

[@ahmedamr5265]

Extremely useful and engaging! thank you :)

w = v(v >= 0); didn't work in my editor or command window. Was I supposed to spend another two lines setting a value to w and v?

[@fitzlellc3599]

You need to have a vector v for that line to work. Try v = randn(1,20)

This was a great tutorial...thanks for sharing.

How do you apply logical indexing in Tables?

[@fabianrestrepo82]

Hello Mike. One question. What is the difference of using jj = jj+1 every other iteration and using w(end + 1) to reference the new element of w. Thanks

very enjoyable .......good work sir

Great stuff. Thanks so much for your time and effort. If i wanted to record the positions of lets say nonzero elements in an array, how can I do that?

[@rubenayla]

You could use a for loop and check every element or use this es.mathworks.com/help/matlab/ref/find.html k = find(X,n) returns the first n indices corresponding to the nonzero elements in X. As an example: a = 2*rand(16,1)-1 indexes = find(a > 0)

Idk if that's scripted or not @4:17 , but it still made me chuckle, good one lol.

[@oliverburke]

So many bits in it were funny. I like learning from Mr. Mike Fitzpatrick.
